Before preparing to sneak into the Unharmed Building, Wu Chang had also made some preparations. He had specially let a Middle Grade Upper Rank Spiritual Array Master come and check out the spots so that he had some understanding of the Spiritual Arrays around the Unharmed Building.
According to the Spiritual Array Grandmaster, the Spiritual Arrays around the Unharmed Building were only mid-grade, so it was not difficult to break them. This Spiritual Array Grandmaster told Wu Chang the method to break them in detail.
At this moment, Wu Chang was prepared to follow the instructions of the Spiritual Array Grandmaster and silently break a hole in the middle grade Spiritual Array of the Unharmed Building. From there, he would enter and plunder the medicinal pills of the Unharmed Building to his heart's content.
